Powder Bed Fusion Techniques in Metal 3D Printing: A Review

Applied Mechanics and Materials
The use of 3D printing (additive manufacturing) with metal has grown significantly in demand recently, greatly reducing the time and expense required to produce complex interconnected metal components. This method minimizes material wastage, facilitates material recycling, and eliminates the need for support materials.

Penetration Study of Liquid in Powder Bed for 3D Powder-Bed Printing

2020
Powder-bed 3D printing technology is attractive as it allows to build complex structures and optimize cost and time. The liquid is sprayed to bond the powder bed at pre-determined positions layer by layer. After print, the non-bonded particles are removed during post-processing.
